BottomofForm
原文中,plan--convertseveralunoccupiedofficebuildingsitownsinCenopolisintohotels。
goal--maximizeitsrevenuesfromtheseproperties。
评价题正确答案需要与plan高度相关,plan出现的关键词unoccupiedofficebuildings和hotels。
A, population明显无关。
C othertravel-relatedservices明显无关。
Dinothercities,讨论对象转移。
E,hotelsthatwerebuiltashotels无关。
其实原文还暗含了比较,要增加收益是相对于原来写字楼的用途而言,所以答案猜测要么和hotel收入有关,要么和office收入有关。
